How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. Tell us when the home is open so we can plan around it.
New build mastic in Dundonald
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you have kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles, we can put it right, on skirting & floors, kitchens and plot handovers alike.
Work in a place like Dundonald is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Why act early in Dundonald
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours in a single home from start to finish. Outside jobs in Dundonald need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Let us know about parking restrictions
- Clear the area around the work
- Mention any tricky access
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Advice
New build mastic in Dundonald: local notes
Dundonald is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Barassie station, it’s worth checking the sealant early, while snags are still fresh. In and around Dundonald, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.

That depends on the sealant. Some smell for a while, some hardly at all.

Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ventilate bathrooms well, especially in the first year
- Photograph failed sealant before it’s redone
- Raise failed sealant with the developer while you’re covered
- Check bath and shower seals every few months as the house settles
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
